Hunt Valley, Md - (May 1 2015) The Junior Science and Humanities Symposium also know as JSHS is a tri-service - Army, Navy and Air Force - program that encourages high school students to conduct original research in the fields of science, technology, engineering and mathematics (STEM).
Two STEM Expos were held in October 2015 for the K-12 students of Galena Park and Pasadena, Texas, through partnership with Communities In Schools. The events were supported by funding from an American Chemical Society grant.

A few species of palms grow what are called 'heels'.
I took 2 minutes to sketch a simple diagram with a Sharpie to show folks what a 'palm heel' that haven't seen one before. In certain species of palms the stem grows at a downward diagonal for a few years before the plant is ready to form a trunk. This stage can last for as little as two years or as long as twenty years.
For the horticulturist, the heel stage can be humorous and confusing. The above ground portion of the palm can move up to a few feet from where it was originally planted! A potted heel-forming palm seedling may eventually warp its container into oval shape or sometimes force the base of their heel through the bottom as it moves diagonally downward.
Palm biologist Dr. Scott Zona explains, “The "heel" doesn't really have a special term: it's simply the stem of the palm. It is positively geotropic early in life and then changes direction (how it "knows" to do this, nobody knows). LH Bailey called it the "saxophone" stem, which is a fairly apt description of the shape. It must have some ecological advantage, esp. in unstable soils, dry habitats, etc.”
Examples of genera that have this behaviour is diverse: Dypsis, Rhopalostylis, Sabal, and Attalea. However not every species within these genera will form 'heels'.

“Naval Air Station Oceana in Virginia Beach, Virginia hosted its annual Air Show drawing more than 280,000 visitors from 25 states and 12 countries over the three day event that is recognized as the Navy’s largest open house in North America. This year, the NAS Oceana Air Show forged a ground-breaking partnership with the Virginia Beach City Public School System (VBCPS) to create a one-of-a-kind “Outdoor STEM Laboratory” on an unprecedented scale. Recognizing the need to highlight career fields in Science, Technology, Engineering and Mathematics (STEM) to America’s youth, the leadership of NAS Oceana and VBCPS committed to creating this Outdoor STEM Laboratory for every 5th grade student in Virginia Beach during the Friday practice air show on board NAS Oceana. The entire 5th grade class – totaling more than 6,500 students –attended the Friday air show for a full immersion in STEM displays, flying performances, ground static displays and a performance by the U.S. Navy Blue Angels flight demonstration team. The goal was to provide each student at least three meaningful STEM interactions via more than 100 “access points” positioned on the flight line within four STEM zones. These displays were set up to educate and inspire our students to consider STEM fields of study with hands-on experiences in physics, robotics, 3D printing and much more. “

Ursuline celebrated STEM Day on Wednesday, March 24. Hands-on experiments taught students about science, technology, engineering, and math in creative ways.
Precious Garley goofs around with one of the 3-D print designs during a visit to the Technology Innovation Sandbox in the library of Penn State College of Medicine on Tuesday, Nov. 13, 2018. Twenty-five students from the Milton Hershey School spent the day at Penn State Health, which teamed up with the American Heart Association and Centric Bank to host the first regional STEM Goes Red event, the aim of which was to empower young women to improve heart and brain health through pursuing careers in science, technology, engineering and math.
Freesia is a genus of 14-16 species of flowering plants in the family Iridaceae, native to Africa. Of the 14 species, 12 are native to Cape Province, South Africa, the remaining two to tropical Africa, one species extending north of the equator to Sudan.
The genus was named in honor of Friedrich Heinrich Theodor Freese (1795-1876), German physician.
They are herbaceous plants which grow from a corm 1-2.5 cm diameter, which sends up a tuft of narrow leaves 10-30 cm long, and a sparsely branched stem 10-40 cm tall bearing a few leaves and a loose one-sided spike of fragrant narrowly funnel-shaped flowers.
Thanx for all the beauty, the comments and invites, M, (*_*)
FOR ALL THE LOVELY DETAIL AND GREAT EXPERIENCE:

Elementary teachers learn how they can teach concepts related to sound and waves. The K-5 STEM project is a three year project that includes 67 elementary teachers and is led by scientists, mathematicians and educators from UW Oshkosh.
Titan-style drop-clamp stem head that I made as a request for someone. I decided to hide the clamp bolt though instead of hanging it exactly off of the bottom like the original.
The 18th Annual Cal State LA MESA STEM Day in Partnership with Boeing will be held in person on October 1, 2022, from 9:00 a.m. -1:00 p.m. This event kicks off the MESA College Prep Program at Cal State LA partner schools. Prospective students from middle school to community college are invited to take a closer look at Cal State LA, College of ECST, and The Boeing Company. www.calstatela.edu/ecst/success/mesa-stem-day
